2 SAFETY INSTRUCTIONS
2.1 GENERAL
• Read through this instruction book carefully and make
sure you understand the contents before using the tiller.
• The tiller must only be used for gardening purpos es.
• Keep children away from the tiller.
• Do not allow children or persons who have not read the
instructions to handle the tiller.
• The tiller is manufactured in accordance with current
standards, and must not be modified or rebuilt.
• All the symbols on the tiller should be kept intact.
• The user is liable for damages incurred by a third party.
WARNING for petrol. Petrol is highly inflammable: Petrol must be stored in the requisite contai-
ners.
• Always fill-up outdoors and with the engine switched off.

should always be tight.
• Only use genuine spare parts wh ich are in good condition. Spare parts must not be rep aired. They must be replaced if they are defective. Poor quality spare parts can lead
to personal injury. If the muffler is damaged it must be replaced.
• The engine must be stopped an d the spark plug lead disconnected in the following circumstances:
When adjusting the rotors.
When the machine is to be cleaned or repaired. When
checking after a collision with a solid hard object. Carry
out the necessary repairs before continuing to work.

ENGLISH
5.3 SUPPORT WHEEL, SEE FIG. 5
Fit the support wheel according to the figure. Do not tighten
the nut (5) too hard. It will not be possible to fold the wheel
arm up.
5.4 FILLING THE OIL, SEE FIG. 2
Remove the plug (12) and fill up with 0.7 L of oil, SAE
10W40. Screw the plug back on.
5.5 ROTORS AND SIDE ROLLERS, SEE FIG. 6
The first rotor (1) is pushed on the axle shaft (2) and locked
with the cotter (3). After which the second rotor (4) is inserted in the first and locked with the cotter (3). Max. 3 rotors
can be fitted in this way on each side. Finally, fit the side rollers in the same way.
WARNING! Check that the cotters are locked,
i.e. that the springs are locked round the shaft.
6 OPERATING
See also section 2.3.
WARNING! Check the engine's oil level. See section 8.4.
6.1 FILLING THE FUEL, SEE FIG. 7
See the safety instructions in section 2.1. Fill up with 2.8 L
of unleaded petrol, and screw on the filler cap.
NOTE! Remember that standard unleaded petrol is perishable. Do not buy more petrol than what can be consumed in 30
days. Environmentally adapt ed petr ol (acr ylic petrol) can be
used to advantage. This petrol is more environmentally-friendly.
6.2 ST ART
See the safety instructions in section 2.3. A cold engine is
started as follows:
1. Open the petrol cock. See fig. 8.
2. Set the choke lever in the choke position. See fig. 11b.
3. Set the throttle control to idle. See fig. 10.
4. Pull the starter handle, first gently until the pawls grip,
and then with a strong tug until the engine starts. See (5)
in fig 2.
NOTE! Do not let go of the cord when the engine has
started, but follow it back slowly with your hand!
5. Set the throttle control in mid position.
6. Set the choke in position "Ru n". See fig 9. A warm engine
is started in the same way as above, but without steps 2
and 6.
6.3 FORWARD OPERATION, SEE FIG. 2.
Forward gear is selected when the left handle, the gear control (2), is not pushed in. The tiller starts forward when the
clutch handle (1) is pulled in. Go forwards as follows:
1. Set the throttle control (10) in the required position.
2. Pull in the clutch handle (1). The tiller stops moving forward when the clutch handle (1) is released.
6.4 BACKWARD OPERATION, SEE FIG. 2
WARNING! The gear control (2) must only be pulled in when the clutch handle (1) is not pulled in.
Go backwards as follows:
1. Set the throttle control (10) in the required position.
2. Pull in the gear control (2).
3. Pull in the clutch handle (1). The tiller stops moving
backwards when both handles are released.
6.5 STOPPING, SEE FIG. 11
Stop the tiller as follows: 1 Set the throttle control in stop position. See fig. 11a 2 Set the choke lever in choke position.
See fig. 11b. 3 Close the petrol cock. See fig. 11c.
6.6 OPERATING TIPS
The rotors drive the machine fo rward. The speed of the rotors
is regulated with the throttle control.
WARNING! Keep hands and feet away from the
rotors.
Adjust the number of rotors on each side to the required working width. See section 5.5.
When the machine is braked with the help of the tail brake,
the rotors dig down into the earth. The working depth depends upon how much the tail brake is forced down into the
ground while working. The correct working depth determ ines how easily the work is done. The optim al working depth
varies with the ground conditions. Try it and see.
Never use the machine in wet soil. Lumps form, which are
then difficult to crush. Hard and dry soil necessitates making
a second run, at right angles to the first.
WARNING! Never overload a new machine. Run
the machine carefully the first 5 hours.
7 STORAGE
The tiller should be stored in a dry place.
See also section
2.4.
After the petrol has been drain ed off, start the engine and allow it to run until all the remaining petrol is used up.
ENGLISH
